Where this comes from

The same registry NdovuSEOLabs uses to classify crawler traffic in your server and CDN logs, built from the operator’s own documentation.

Registry version 2026-10-29.1

See which of these crawlers visit your site.

Crawl Analytics reads your own server and CDN logs and checks each claim against the operator’s published IP ranges and DNS.
